NEES

The George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) is a national network of shared facilities and tools, and a centerpiece of the NSF effort to understand earthquakes and prevent or mitigate the damage they cause. NEES sites across the United States feature shake tables, geotechnical centrifuges, a tsunami wave basin, large-scale testing facilities, and mobile and permanently installed field equipment. Together they help researchers understand how earthquake and tsunami forces affect ground motion and soil liquefaction, the built environment--such as buildings, bridges, and utility systems--and nearshore and coastal environments.

The Large Scale Structures Laboratory features a biaxial, multiple shake table facility (with three identical biaxial shake tables) capable of earthquake testing conventional structural and non-structural systems by using the tables separately or as a single unit....
